The 292 Pertronix will work as long as you have the same smaller distributor but I recommend an HEI for reliability and ease of the availability of parts as well as overall increase in performance.
I did find an HEI on ebay for like $400 at one time...I'll have to search for it. I put a 600 edel on my 292 6 banger in my 66, works fine and helped alot..also has hei and headers. I believe I have the smaller dizzy, I used my 292's neww set of points and cap and all fit fine.
